Clinical Trial Summary

The impact of the coronavirus disease (COVID)-19 pandemic on global healthcare systems has prompted a search for novel tools to stem the tide. New digital health tools can provide possible health solutions in this time of unprecedented medical crisis to mitigate the impact of this pandemic. This proof of concept study will determine the feasibility and effectiveness of implementing a mobile application for contactless screening and vital signs measurement (MAC-VITAL) such as blood pressure (BP), heart rate (HR), respiratory rate (RR), oxyhemoglobin saturation (SpO2), temperature from surgical patients peri-operatively. Contactless measurement of vital signs will bridge the current gap between virtual care and in-person medical assessments.

Description:

This study aims to determine whether a mobile app can accurately and reliably measure vital signs without any person to person contact, and the feasibility of implementing it in a peri-operative setting (e.g., during COVID-19). The validity and feasibility of the Anura™ Research app will be assessed during inpatient visits in preparation for and after surgery, and it will be compared with standard medical monitors.
